Setup Zoned OCR dialog box

Set up specific zones to be processed during recognition on this dialog box. You can preview the document that is similar in structure to the documents that will be processed, navigate through its pages (if it is a multipage document) and select zones for recognition. During processing the component will try to recognize each zone, and if any text is found it will be assigned to an appropriate RRT. The text can be also saved into a CSV file.

Image pane

Image pane displays the image and allows you to navigate through its pages (if it is a multipage document) and select zones. The image is displayed after applying preprocessing options specified in the Advanced tab. Select any number of zones by holding down the right mouse button and dragging the pointer.

In the right-top area of the dialog you can read the following information: zones on the selected page to recognize with their alignment, zones that will not be recognized on this page.
